John Hewson’s extraordinary attack on rival solar storage technologies – including the suggestion they are not bankable – has stunned the industry. They are keen to know how Solastor’s technology – described just three years ago as “an expensive way to boil water” can now deliver the world’s cheapest 24/7 solar power.

Malcolm Turnbull hints that he wants an energy revolution, but he might not get one unless the hard right rump in the Coalition get on board. The conservatives should look to West Australia, where one of their own has embraced renewables as a solution to the spiralling costs of fossil fuels.

The CEO of New Zealand network operator Vector intends to broaden the rollout of its solar storage leasing package, and expects up to a third of all consumers will generate and store their own electricity. He says too many networks are locked in an old paradigm, shovelling “dumb capital” into legacy assets and passing the cost on to consumers.
